Hi Michealegl, like others have said you're still young really, I think 50 is the new 40, or maybe even 60 is? Backs can be an issue for a lot of people, many younger than you, I hear yoga and pilates are particularly helpful, maybe give them a go?
I'm 72 and healthy but not fit, I still work part time and haven't seen a GP in about 10 years. Started having a few problems and now 3 weeks on from a telephone consultation (with a GP I've never met as my previous one retired about 8 years ago) I've had blood tests, an ECG, heart scan and seen a Cardiologist. I've been diagnosed with AF and an irregular heartbeat and on 3 lots of medication - I feel like a drug addict!
It's quite a wake up call, especially as it's possible I may also have heart failure. So I've cut down on the wine, started some gentle exercise with an on line cardio rehab physio's app and will stop taking life and health for granted. I have 3 AC and 5 DGC, 17, 15, 13,11 and 4 months, plus my lovely hubby, sisters etc. I'm a bit taken aback that my travel insurer of many years won't cover me for anything to do with my heart condition so will have to look around as I'm far too young to give up on foreign travel - and besides my DD and family live in Spain! As they say old age isn't for wimps. not that I'm old yet you understand
